Scientific and Medical images

I was browsing on the web and found a site that offers scientific images for sale. I saw these and saw great potential to use them for my own site to enhance the learning of students. and offer for sale highly accurate images that are suitable for professional or medical use. I decided to use quite a few on the site to brighten it up and make it more appealing to others. The owner of the site was extremely helpful and even changed the labels on the heart diagram so that they matched the UK curriculum.
